This barrel roller bearing accommodates angular misalignment between shaft and housing through its curved raceway geometry, allowing operation under shaft deflection without edge loading. Bore diameter is 85.0 mm, outside diameter is 150.0 mm, and width is 28.0 mm. The bearing has a tapered bore (K) for mounting on an adapter sleeve, a machined brass cage (MB), and a net mass of 2.14 kg. Limiting speed is rated at 4750 1/min. Radial internal clearance C3 (Group 3) provides increased clearance above standard, compensating for thermal expansion during operation and supporting the self-aligning function under load. The tapered bore with K designation permits axial displacement for clearance adjustment during installation on a sleeve, while the MB cage suits moderate to higher speed operation within the stated limit. The design suits applications where shaft bending or housing misalignment must be tolerated without additional external alignment correction.
